Don't know exactly what command you're typing but typically on a dual proc machine a kernel would be built something like: make depend make -j8 make install or the world might be built: make -j8 buildworld make installworld It is generally recommended to start about 4 threads on a single proc and 6-10 on a dual, to make most efficient use of the processor and IO systems. There shouldn't be a space between the j and the number, BTW. Or, at least I never put a space there. If none of this helps, maybe you could paste in exactly what commands you're typing and what error messages it's giving you..
